Seller not responding

[oke_acton]

I won an auction four days ago and immediately paid and contacted the seller. It was a Thursday. Today is Monday. They have yet to respond to my 3 messages I have since sent about the item, and 1 asking why they were not responding.

Am I being impatient or should I be worried? The seller had 100% positive feedback, but I later realised they had only 9 transactions, one as a seller with which the buyer was satisfied.

Thanks guys!
